SWITCHING DEVICE FOR THREE-POSITION SWITCH MANUAL OPERATION MECHANISM AND BUS ROOM OF GAS-INSULATED SWITCHGEAR

摘要

Disclosed is a switching device (500) for a three-position switch manual operation mechanism for realizing a vertical installation. The switching device comprises a supporting frame (510), an operation panel (520), a transmission gear (530), a positioning and limiting plate (540), a switching mechanism (550), a positioning pin (560), a supporting plate (570) and an operation mechanism (580) of the switching device (500). The operation direction is switched via the transmission gear (530), the mechanism is positioned and limited via the positioning and limiting plate (540), and the switching device (500) is freely switched between an ¡°operating position¡± and a ¡°rest position¡± via the operation mechanism (580) of the switching device (500).
